Abstract:
Objective]To evaluate the value of three-dimensional transesophageal echocardiography(3D-TEE)in the applica?tion of percutaneous left atrial appendage occlusionin patients with atrial fibrillation.[Methods]7 patients with atrial fibrillation in Da?lian area(female 4,male 3,mean age 71.5 ± 3.3 years)were enrolled in the study.The maximum and minimum diameter and the max?imum depth ofleft atrial appendage were measured by 3D-TEE,and export morphology and leaf number were viewed.WATCHMAN occlude size was selectedby 3D-TEE. The process of operation was monitored by 3D-TEE. 3D-TEE was also performed in 3 months after the transcatheter closure.[Results]7 patients were performed the transcatheter closure therapy successfully. Preoperative 3D-TEE showed left atrial appendage export:5 cases were oval,and 2 cases were nearly circular. The leaf number was 1.6 ± 0.8. The maximum diameter of the left atrial appendage export was(23.1 ± 1.7)mm,(19.2 ± 2.1)mm minimum diameter,maximum depth of(27.6 ± 3.3)mm. The maximum diameter had good correlation with the size of occluder(r=0.944,P=0.001). 3D-TEE was used for guidance in the transcatheter therapy and succeeded. There were 1 case with little shunt after the transcatheter closure. 3 months af?ter the treatment ,position and shape of the occluderswere all in good.[Conclusion]3D-TEE has the great value in the percutaneous closure of left atrial appendage.
